| Spira
is a young company that is gaining national
attention with its remarkable athletic running and
walking shoes. The company is premised upon a
proprietary unique shoe technology called
WaveSpring™. Energy that is otherwise lost to
the ground is recycled to the wearer, providing a
remarkable combination of cushioning and energy
return. Spira makes it easier to stand, walk, run
and compete without the stress and fatigue
associated with traditional shoe midsole
materials. Heel and forefoot spring configurations
are engineered for specific activities to meet
individual needs. Sport Biomechanics, Inc. tested
the WaveSpring™ technology and found it had the
highest return of energy of any shoe technology
they have ever tested — 87-96%. |
